APPENDIX A

DEFENSE LOGISTICS AGENCY

DRUG-FREE WORKPLACE PLAN

Appendix A is divided into two sections. Section One involves 

position sensitivity. Section Two involves functions directly and 

immediately related to public health and safety, the protection of 

life and property, law enforcement, or national security.

TESTING DESIGNATED POSITIONS

SECTION ONE

POSITIONS INVOLVING ACCESS TO SECRET OR TO TOP SECRET INFORMATION

This category includes all positions, which require Secret or Top Secret clearance access.

Use of illegal drugs by an incumbent of such a position could result in the compromise of national 

security through impaired judgment and loss of custody or control of sensitive information and 

operations. Drug usage could also result in the sale of classified information to support or conceal a 

drug addiction.

SECTION TWO

FIREFIGHTER, GS-081

SUPERVISORY FIREFIGHTER, GS-081

FIRE CHIEF, GS-081

ASSISTANT FIRE CHIEF, GS-081

LEAD FIREFIGHTER, GS-081

FIREFIGHTER (EMT), GS-081

FIREFIGHTER (PARAMEDIC), GS-081

FIRE PROTECTION INSPECTOR, GS-081

Incumbents are responsible for performing work in controlling and extinguishing fires and rescuing 

persons endangered by fire. Hazards encountered may involve burns and other effects of heat, smoke 

inhalation, falling materials, explosion, and exposure to toxic materials. Incumbents must be prepared 

to deal with fire victims in varying states of fright and panic. Also, they may be required to operate or 

ride trucks at high speed under adverse conditions, e.g., congested areas. These duties require keen 

sensory perception and neuromuscular coordination.

Drug usage could result in loss of life or injury and damage to or destruction of property. Use of illegal 

drugs could endanger fire victims, the general public in the fire vicinity, other firefighters, and all 

property threatened by fire.

GUARDS AND POLICE

POLICE, GS-083

LEAD POLICE, GS-083

SUPERVISORY POLICE, GS-083

Incumbents are responsible for investigating violations of Federal, state, and local laws; security 

controls; and standards of conduct. Incumbents conduct preliminary investigations of serious offenses 

for referral to appropriate investigative agency; conduct preliminary investigations relative to fraud and 

violations of standards of conduct for referral to counsel; and generally conduct complete investigations 

of offenses of a less than serious nature. These duties require defending oneself or others against 

physical attack.

GUARD, GS-085

LEAD GUARD, GS-085

SUPERVISORY GUARD, GS-085

Incumbents are responsible for performing physical security of facilities, property, employees, and 

visitors at DLA activities, and for performing vehicle traffic and parking control. The work primarily 

involves security and protection of facilities and restricted areas to preclude improper access, use, or 

movement of property.

For both guards and police, drug usage could result in loss of life or injury and damage to or destruction 

of property as the positions are directly responsible for protection of life and property and require 

incumbents to carry firearms. Incumbents must maintain a high standard of conduct at all times and the 

use of drugs would interfere with or prevent effective performance of critical duties. The behaviors 

demanded of these employees: remaining calm under pressure, thinking rationally, and responding 

intelligently despite adverse circumstances, and dealing effectively in interpersonal confrontations are 

inconsistent with illegal drug use. Illegal drug usage is clearly antithetical to the law enforcement duties 

of these positions.

EMPLOYEE ASSISTANCE PROGRAM

EMPLOYEE ASSISTANCE PROGRAM COUNSELOR, GS-101

EMPLOYEE ASSISTANCE PROGRAM COORDINATOR, GS-101

EMPLOYEE ASSISTANCE PROGRAM SPECIALIST, GS-101

HUMAN RESOURCES SPECIALIST, GS-201

HUMAN RESOURCES SPECIALIST (EMPLOYEE RELATONS), GS-201

Incumbents provide counseling and referral services to employees for personal problems, including 

alcoholism and drug abuse, which may be affecting their work performance. Incumbents conduct intake 

interviews to determine the nature of the employee’s problem, identify appropriate community 

resources to help the employee, monitor the employee’s progress through treatment, and conduct 

follow-up counseling to ease the employee’s reentry into the workplace. Incumbents conduct drug and 

alcohol abuse training and education for all levels of employees and are responsible for activity drug 

and alcohol abuse prevention programs. Incumbents are responsible for ensuring that the confidentiality 

of Employee Assistance Program client records is maintained.
UPDATED SEPTEMBER 2013

ALL OTHER COPIES OF APPENDIX A ARE OBSOLETE

Drug abuse is inherently inimical to the duties of these positions. Employee Assistance Counselors are 

responsible for preventing and discouraging substance abuse in the workplace, and encourage 

employees with substance abuse problems to enter treatment. The Employee Assistance Program is a 

critical part of the DLA Drug-Free Workplace Program; drug abuse would discredit not only the 

counselor but the entire Program, resulting in an environment in which substance abuse is condoned. 

This, in turn, would pose a threat to employee and public safety wherever there were safety sensitive 

positions and, given the mission of the Agency, could threaten national security through security 

breaches and weakening the activity’s ability to support the national defense. 

MESSENGER (MOTOR VEHICLE OPERATOR), GS-302

MAIL AND FILE CLERK, GS-305

MAIL CLERK, GS-305

MAIL CLERK (MOTOR VEHICLE OPERATOR), GS-305

Testing designated positions include only those Messengers, Mail and File Clerks, Mail Clerks, and 

Mail Clerks (Motor Vehicle Operator) which require operation of a motor vehicle.

Incumbents operate motor vehicles on government installations as well as public streets and highways, 

including intercity travel over interstate highways, and in congested areas to deliver mail, packages, and 

supplies to and between government offices, the U.S. Postal Service, and some commercial businesses. 

Incumbent must operate this equipment in a safe manner, requiring sound judgment and constant 

alertness. The documents handled may include classified materials and sensitive contract information, 

the loss or release of which may harm negotiations or compromise important government contracts or 

national security.

Drug usage could result in loss of life or injury and damage to or destruction of property and loss of 

important Government documents. Drug usage also endangers the lives not only of the operator of the 

vehicle but also of any bystanders and other vehicle operators on government or public streets and 

highways.

NURSE, GS-610

OCCUPATIONAL HEALTH NURSE, GS-610

OCCUPATIONAL HEALTH NURSE (EDUCATIONAL), GS-610

Incumbents must recognize patient’s adverse signs and symptoms to react swiftly in emergency 

situations. They must be able to provide emergency treatment to accident victims and take resuscitative 

measures in case of cardiac or respiratory arrest when a physician is not present or immediately 

available.

Drug usage could result in loss of patients’ lives or patient injury. Additionally, the incumbents’ access 

to medication requires the utmost personal integrity on their part concerning drug usage.
UPDATED SEPTEMBER 2013

ALL OTHER COPIES OF APPENDIX A ARE OBSOLETE

GENERAL INVESTIGATOR, GS-1810

INVESTIGATOR, GS-1810

CRIMINAL INVESTIGATOR, GS-1811

Incumbents perform, advise on, and administer investigations, inspections, and compliance

enforcements concerning suspected violations of Federal statutes and regulations. Close coordination 

must be maintained with U.S. attorneys, military security, and local, state, and Federal law enforcement 

officials. Incumbents interrogate witnesses and suspects, serve subpoenas, testify before grand juries, 

administer oaths, and conduct searches for physical and documentary evidence. Conduct of these duties 

requires the highest level of personal integrity and credibility since it involves investigating and 

charging others who are accused of wrongdoing and violating the law. Incumbents are required to 

possess a secret clearance. These duties also demand consistent exercise of sound personal judgment.

Drug usage could compromise criminal investigations through employee failure to obtain or properly 

evaluate key data or through failure to follow legal procedures and properly execute rules of evidence. 

Additionally, incumbents who are drug users are highly vulnerable to blackmail by those being 

investigated. 

TEST DRIVERS

QUALITY ASSURANCE SPECIALIST, GS-1910

QUALITY ASSURANCE SPECIALIST (MECHANICAL), GS-1910

Incumbents test drive Family Medium Tactical Vehicles, 2 1⁄2 ton and 5 ton trucks, tractors, fuel tankers

and vans. Testing includes driving approximately 6-7 miles around a banked test track at 55 to 60 miles 

per hour, testing brakes, performing a 60 degree hill climb, side slopes, testing for fuel leaks, etc. The 

track is shared with the contractor and there may be up to 12 people on the track at one time. Testing is 

performed on a daily basis. The uncertainties of the testing situation (the vehicles may fail on testing) 

make test driving more hazardous than regular driving and require constant alertness and vigilance.

Drug abuse by incumbents could result in loss of life or injury and damage to or destruction of vehicles 

under testing and surrounding property. Drug usage would endanger the lives not only of the driver, but 

of all other personnel present at the track. In addition to the immediate danger at the track, failure to 

detect vehicle defects due to drug impairment would jeopardize the safety of subsequent drivers of 

tested vehicles.

OPTICAL INSTRUMENT REPAIRER, WG-3306

Incumbents install and synchronize bore sights and bore sight aids in the muzzles of weapons and 

combat vehicles including armored tanks. Incumbents use precision instruments and testing devices to 

calibrate bore sights to meet prescribed tolerances. Incumbents isolate deficiencies and repair or replace 

faulty components. Constant alertness and attention to detail is required to identify deficient 

components, make proper repairs, and accurately calibrate the weapon.

Drug usage could result in loss of life or injury, damage to property, or impair the readiness and 

effectiveness of military warfare. Inattention to defective components or failure to properly repair bore 

sights could result in failure of the weapon in field operations which could result in death or injury to 

military members or civilians in nearby areas.

WOODWORKER BLOCKER AND BRACER LEADER, WL-4604

Incumbents operate heavy saws and pneumatic tools to cut and construct dunnage materials to prepare 

heavy loads such as industrial plant equipment and high pressure steam vessels, etc, for transportation. 

This equipment is both costly and fragile. Incumbents also drive heavy equipment to load and unload 

material, guide equipment to be placed by other equipment operators, operate forklifts, and secure 

equipment to carrier conveyance for over the road, ocean, and air shipment.

Drug usage could result in injury and loss of life as well as damage to or destruction of property. 

Inattention and failure to exercise sound judgment could result in costly accidents, damaging not only 

the equipment or material being moved, but the transportation equipment involved (tractors and trailers) 

and surrounding structures. Such accidents also threaten injury or loss of life to co-workers and to the 

general public as this equipment is transported on public highways.

GENERAL EQUIPMENT REPAIRER, WG-4737

GENERAL EQUIPMENT REPAIRER INSPECTOR, WG-4737

Incumbents of these positions perform repairs, modifications, or inspection of compressed gas cylinders 

consisting of high and low pressure rating ozone depletion chemicals, refrigerants/halon. Incumbents 

perform hydrostatic testing of these cylinders using sensitive testing equipment which must be 

calibrated at least daily. Incumbents recover, recycle, and reclaim ozone depleting chemicals. 

Incumbents must be constantly alert to accurately repair or modify cylinders as well as to calibrate 

testing equipment to close tolerances. 

Drug use in these positions could result in loss of life or injury or damage to property or the 

environment. Inattention to proper calibration could result in inaccurate repairs which could result in an 

explosion causing injury or loss of life or damage to nearby structures or equipment. Failure to properly 

recover and recycle ozone depleting chemicals could result in a release of these hazardous materials into 

the environment.

FUEL DISTRIBUTION SYSTEM WORKER, WG-5413

Incumbent receives, stores, transfers, and issues various petroleum products and other products such as 

liquid oxygen and propane. Incumbent drives vehicles weighing more than 7000 pounds and less than 

22, 000 pounds, including a two and one half ton fuel tanker truck to deliver gasoline and fuel oil 

throughout a large military depot. The incumbent picks up empty forklift propane tanks, refills them 

from a larger propane storage tank, and delivers filled tanks to depot worksites. The incumbent 

personally fills tanks with gasoline, fuel oil, and propane. These duties demand the constant exercise of 

good judgment and skill in transferring and filling tanks to guard against spills and hazards from fire 

and explosion.

Drug usage in this position could result in loss of life or injury and damage to or destruction of property 

through the improper handling of explosive or highly flammable liquids or gases. In addition to the 

requirement for sound judgment and alertness in the operation of the fuel transporting vehicles to

PACKER LEADER, WG-7002

Incumbents operate mobile industrial equipment such as tractor trailers, forklifts, warehouse tractors, 

locomotives, vans, and cars. Incumbent must operate this equipment in a safe manner, requiring sound 

judgment and constant alertness. Motor vehicle operators transport other employees, including activity 

Commanders and other key DLA officials, on official business and transport important government 

documents between DLA activities and buildings. These documents may include classified materials 

and sensitive contract information the loss of which may harm negotiations or compromise important 

Government contracts. Forklift operators transport government property, such as electronic equipment, 

which is both costly and fragile.

Drug usage could result in loss of life or injury and damage to or destruction of property and loss of 

important Government documents. A significant portion of the reported mishaps in this Agency involve 

employees in these positions, frequently as a result of operator error or inattention. Because of the 

military support functions of this Agency, property damage from these accidents can adversely affect 

military readiness through the loss of critically needed and otherwise unavailable supplies. Drug usage 

by operators of mobile equipment endangers the lives not only of the operators and any passengers, but 

also of bystanders. In addition to the hazards posed by operators who doze or fail to observe traffic 

while driving, failure to properly set brakes has resulted in vehicles driving uncontrolled through walls 

and into adjacent building and other structures.

WEAPON REPAIR

Includes:

ARTILLERY REPAIRER, WG-6605

SMALL ARMS REPAIRER, WG-6610

SMALL ARMS REPAIRER FOREMAN, WS-6610

makes and models of mortars, recoilless rifles, and hand and shoulder weapons including rocket 

launchers. Position requires vigilance, alertness, and attention to detail to identify dangerous or 

defective parts, to properly diagnose and repair weapons, and to use sensitive calibration equipment to 

properly adjust repaired artillery.

Drug usage could result in loss of life or injury and damage to or destruction of property. Inattention 

due to drug use could result in failure to reject dangerously defective parts or to properly repair and 

calibrate the weapons. Any consequent failure of artillery, rocket launchers or other weapons in live 

field operations could result in catastrophic loss of life of military members or the civilian population in 

nearby areas and destruction of the artillery and weapons themselves and surrounding structures and 

weapons as well.

Incumbents working with hazardous materials receive, store, assemble and pack for issue or shipment, 

and ship hazardous, explosive, and toxic materials. This includes stacking, palletizing, placing, and 

arranging such items in storage locations in such a way as to avoid tipping, crashing, or damage. 

Incumbents must be alert to and report damage or deteriorated stock or hazardous conditions in the 

physical plant. Hazards materials examiners handle, accept, or reject item such as explosives, toxic 

chemicals and flammables, gas cylinders, and classified and high value equipment. 

Drug abuse in these positions could result in loss of life or injury and damage to property through 

improper handling of explosive, toxic, or highly flammable materials. Inattention due to drug use could 

result in failure to reject dangerously defective materials or to properly identify hazardous items and the 

safeguards necessary for their safe storage and shipping. Any consequent explosion, fire or leaking of 

toxic materials would threaten injury or loss of life to bystanders, damage to supplies and equipment 

required by the military, and possible contamination of the surrounding environment.

For the 0028 and the 1104 series, incumbent serves as activity focal point for hazardous property and 

arranges for the disposal of hazardous wastes. Incumbent inspects hazardous products to insure proper 

identification, labeling, and containment. Incumbent determines whether containers are safe to handle 

and inspects for leaks. Incumbent serves as emergency spill coordinator at the worksite, with 

responsibility for the prevention, control, and cleanup of pollution caused by spills, leaks, vapors, and 

waste disposal. Position consequently requires vigilance, alertness, and attention to detail to identify all 

potential hazards and to react immediately, appropriately, and safely to leaks which may occur at any 

time.

Drug abuse could result in loss of life or injury and damage through release of toxic or highly 

flammable materials into the environment or failure to take prompt action to correct such spills.

SUPERVISORY DISTRIBUTION FACILITIES SPECIALIST, GS-2030

Incumbents operate materials handling equipment, which includes hybrid aisle cranes as well as 

standard forklifts, to store and retrieve parts and supplies in a high-rise storage are for frequently 

requested defense material. The incumbents operate the aisle cranes at heights of up to 60 feet. 

Incumbents are required to operate this equipment in a safe manner which requires sound judgment to 

avoid overloading the crane. The materials transported are urgently needed items of defense material 

and may be expensive and fragile. The aisle cranes service the most requested defense supply items, 

with surges of up to 750 “Hot” tickets in a day. These items must be picked up and shipped overnight. 

These requests may be Presidential, emergency, and/or NASA. Each aisle within the high rise storage

area contains an average worth of between $7 and $14 million dollars of necessary defense supplies.

Drug abuse in these positions could result in both a threat to safety and national security. A threat to 

national security is present through the risk of damage to the aisle crane equipment and loss of access to 

substantial quantities of urgently needed defense material. Aisle cranes are difficult and expensive to 

repair and replacement cranes are not readily available. Drug-induced impairment could easily result in 

the dropping or knocking over of qualities of small items, such as bolts. Driving over these items could 

cause serious damage to either the aisle crane or the rails on which it runs, removing the crane from 

operation and leaving the items in that aisle inaccessible until the crane and/or rails were repaired or 

replaced. The loss of access to an entire aisle of material for any extended period of time poses and 

unacceptable risk to this Agency’s ability to provide essential logistical support to America’s Armed 

Forces. The inability to provide essential defense material to the military services in a timely fashion 

presents an intolerable threat to the health and safety of our military service members and to the national 

security. Drug use is these positions could also lead to loss of life or injury as well as damage to or 

destruction of property. Inattention to safe operating procedures or improper use of safety equipment 

could cause an accident resulting in loss of life or injury or damage to the equipment being operated as 

well as the materials being transported.
